iMessage on TV?

I have been wondering for a while..... Why is there no messaging App on the new TV? It would make perfect sense. I mean we have the Siri Remote which we could use for voice messages.
It just got me curious. Do you guys think this is something we will see in the future?

Have you had Siri give 100% accuracy when dictating? That's probably why

Evidently the new beta of tvOS has Bluetooth keyboard support so it could be something added at some point. But I'm with D saying I wouldn't use it. As long as you can disable notifications it shouldn't affect viewing content but to me the issue is the tv isn't as personal as my own iOS device(s).
